[PATCH] GenWQE: Use pci_enable_msi_exact() instead of pci_enable_msi_block()

[PATCH] GenWQE: Use pci_enable_msi_exact() instead of pci_enable_msi_block()

[Alexander Gordeev]

As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range()  or pci_enable_msi_exact()
and pci_enable_msix_range() or pci_enable_msix_exact()
interfaces.

fine with me, if it works like it did before.

I forgot to CC linux-pci mailing list.
I will resend this patch with Frank's ACK after v3.15-rc1.

Thanks!
